What is parasympathetic?

What Does parasympathetic Mean

Parasympathetic is an adjective that is used to describe the sector of the autonomic nervous system whose centers are found at the ends of the cerebrospinal axis and which functions as an antagonist of the sympathetic system . It is made up of nerves that originate from the spinal cord and brain.

Greek roots are those that have the term parasympathetic. Thus, we can establish that it was formed from the prefix “para-”, which means “against” or “beside”; from the particle "syn", which is equivalent to "together"; of the verb “pathein”, which is synonymous with “feel”, and of the suffix “-ico”. The latter is used to indicate "relative to".
It is important to mention that the autonomic nervous system is in charge of the control of the involuntary functions of the organism . This means that it regulates the heartbeat, blood pressure, body temperature, and digestion, for example. Two parts of the autonomic nervous system are recognized: the parasympathetic nervous system and the sympathetic nervous system .

The tasks performed by the parasympathetic nervous system are the opposite of those performed by the sympathetic nervous system. While the parasympathetic system is responsible for decreasing the heart rate, the sympathetic system increases it, to mention one case. By working together and in a coordinated way, both systems allow the body to respond to different situations and can adapt to varied circumstances.
The parasympathetic remains active while the body rests and during the development of the digestive process. It is responsible for stimulating digestion, defecation and urination and lowers the heart rate, respiratory rate and blood pressure . It also contracts the pupils .
In the same way, the parasympathetic nervous system is also responsible for allowing sexual arousal or stimulating the production of saliva, among other things.
At a general level, the parasympathetic system is dedicated to the stimulation of those processes that contribute to saving or storing energy . Its purpose is to guarantee well-being in the long term. The sympathetic system, on the other hand, aims to solve incidents in the short term.
In addition to all the above, it is important to know that the parasympathetic nervous system is made up of four different areas: the sacral, the hypothalamic, the midbrain and the rhombencephalic. The latter is the one that is made up of nerve fibers that come to run through what are various nerves of the brain.
Of course, it should not be overlooked that there are two types of neurons in particular in the aforementioned system. Thus, on the one hand, there are the ganglion cells, which are short and are responsible for carrying out the release of acetylcholine. And, on the other hand, there are the so-called pre-ganglionics, which are long and are located very close to what is the cerebrospinal nucleus.

It is curious to note that people who have some type of alteration of the parasympathetic nervous system find in music a very therapeutic element. Yes, because different studies carried out by organizations such as Harvard University have determined that music helps them calm down.
